Oris BC3 Day Date | Time to clean the air | No. 42

Ouch. When this BC3 Day Date pilot’s watch landed at our Hölstein HQ, it looked like it had crash landed. The brief: clean it up, get it flight-ready again. Possible? We like a challenge. Have a watch to see if we gave this one back its wings. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// ►PRODUCT INFORMATION Model: BC3 Day Date Ref.
